she's the exact person who'd drive two hours there and back for food.
That was back when she was doing vlogs, and still put effort into her channel, shitty though it was. Now she's doing cocaine (though not addicted to it, I don't think). She's got a new high she's chasing, and the "oh I just felt like 4-hour round trip two days in a row" explanation is a thin one. She can drive anywhere whilst livestreaming and still get the same engagement. Why increase her expenses and waste her time when no one really gives a shit about Montreal, including herself?
No, I'm sorry. This feels different, and we
know it's different. We can't trust what she says, but we can still think logically.
Are her members seriously cool with her taking up smoking?
She's smoked weed before. Some people take issue with it, but they're pretty quiet. Most people left in her chat are the "LET HER DO WHAT SHE WANTS, SHE'S AN ADULT" enabler type. Also, you may be confused. They're not tobacco cigarettes, although she's probably smoking those too, according to some of her stories.
if a Tinder guy with a ‘party’ bio says he can fix her up, she will do the four-hour trip to get drugs off him rather than find another way.
I think this "habit" was something she kind of fell into. We also know she's a creature of...well, habit, who avoids discomfort at all costs. And I think we're ignoring how much of this is her addiction to Nader. Attention is her drug, above anything else. Cocaine might feel nice, but it doesn't get her attention unless Nader's there (or her chat, in a pinch).
All of this to say, she associates the habit with Nader. She's basically doing cocaine because of Nader. Nader is her hookup. Even though she had a massive falling out with Nader, she still contacted him for drugs. As uncomfortable as that would have been, seeking someone other than Nader would be not only that much more uncomfortable, but also risky. Besides, when have we seen Chins show any signs of genuine agency or initiative?
She's gonna go with what she knows, and what will get her what she wants.
Edit: and I know a lot of you disagree with me about this, but I believe a desperate, drug-addicted, sex-addicted Chins was Nader's plan all along, and he's going to use this situation to his advantage, as he has all along. He's two steps ahead of Chins, and she's already easily manipulated. I don't necessarily think the mule thing is between supplier and dealer, but perhaps just between friends, which live in Montreal. No need to drive the distance when Chins is ready and willing, and she'd have no one to answer to but Nader.
